This proposed AD was prompted by a manufacturer investigation that revealed Teflon material in the A-sump oil strainer (strainer assembly) screen after several reports of in-flight shutdowns (IFSDs) and unscheduled engine removals (UERs). This proposed AD would require initial and repetitive visual inspections of the strainer assembly screen. As a terminating action to the initial and repetitive visual inspections, this proposed AD would require the replacement of the stationary oil seal at the No. 1 forward bearing. The FAA is proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Airplanes
Document Number: 2021-18110
Type: Proposed Rule
Date: 2021-08-24
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2018-19-28, which applies to certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes; and AD 2014-16-16, which applies to all of those airplane models. AD 2014-16-16 requires, for certain airplanes, retorquing and replacing the pylon lower link fittings, and for all airplanes, repetitively retorquing those fittings. AD 2018-19-28 requires modifying the attaching parts of the pylon lower link fittings. Since the FAA issued AD 2014-16-16 and AD 2018-19-28, the FAA finds it necessary to change the compliance time for the modification. This proposed AD would require an inspection of certain shear pins, replacement if necessary, and revised compliance times for the modification, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

Type: Proposed Rule
Date: 2021-08-24
Agency: Federal Aviation Administration, Department of Transportation
This action reopens the comment period for the Safety Management System for Certificated Airports SNPRM published July 14, 2016. In the SNPRM, the FAA proposed to amend certain requirements included in the notice of proposed rulemaking published on October 7, 2010. Most notably, the FAA revised the proposed applicability of the rule so that a Safety Management System (SMS) is only required for a certificated airport classified as a small, medium, or large hub airport in the National Plan of Integrated Airport Systems; serving international air traffic; or having more than 100,000 total annual operations. The FAA also proposed changes that would extend the implementation period from 18 to 24 months; require submission of an implementation plan within 12 months instead of 6 months of the effective date of the final rule; modify the training requirements; ensure consistency among various FAA SMS initiatives, and reduce the implementation burden.
